VALVE.

Specification of Letters Patent.

Patented Dec. 143., 1915.

Application filed June 19, 1913. Serial No. 774,612.

tain new and useful Improvements in Valves, of which the following is aspecification.

This invention relates to improvements in valves'and has particularrelation to valves that are used in connection with irrigating systems,especially where means is required for controlling the flow of waterfrom stand pipes or other outlets, as when it is desired to direct thewater through surface piping, hose or the like. I i

It is an object of the invention to provide a valve mechanism which canbe secured to the end of a cement or other outlet pipe and which isprovided with a slide adapted to out 01f water which would otherwiseflow from said outlet, a .mechanism also being adapted to receive theend of'a pipe or elbow for directing the water to desired points. r 1

It is also an object of the invention to provide a valve mechanism witha casing having upper and lower sections and an intermediate slideforminga valve, the mechanism also having means for forcing one membertoward the other to make a water tight oint at the slide'or valve.

With these and other objects in view, the invention consists in certainnovel combinations, constructions and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing forming a part of this specification: Figure1 is a side elevation of a valve mechanism constructed in accordancewith the present invention, a

portion of a stand pipe being shown, andan elbow also being shown inposition.- Fig. 2 is a verticalsectional view through the mechanism, amodified form of clamping means being shown however. Fig. 3 is atransverse sectional view taken upon the Fig. 1 is a similar transversesectional view but showing a removable slide' valve instead of a pivotalone.

Fig. 5 is a side elevation of a valve mechanism having a cam ring forclamping the parts together. Fig. 6 is a side elevation of the uppermember of the valve mechanism showing the cam ring from another Viewpoint.

The valve mechanism of the present invention is designed for usewherever the flow of liquids from one pipe into another is to becontrolled but is especially well adapted for use in irrigating systemswhere vertical stand pipes project above the ground and where it isnecessary to connect 'surfacepiping with the stand-pipe for directingwater to any given points.

The details and features of the invention will now be more specificallydescribed, reference being had to the drawing in which 5 indicates alower valve member, 6 an upper valve'member and 7 a valve proper. Thelower member 5 is preferably in the form of a cap ring having a flange 8adapted to fit over the end of stand-pipe 9. Such standpipes are usuallyof cement concrete and the cap ring or member 5 is usually secured uponthe upper end of the said stand-pipe 9 by cementing it in place. Theupper surface of the member 5 is provided with a vertically extendingannular flange 10 surrounding the opening in said member. The flange 10is preferably beveled at 11 upon its upper peripheral edge so as tofacilitate the insertion of the valve between the said and 6. Pro ectingupwardly members 0 from said member 5 are standards or bolts 12 whichare-usually secured in thickened portions or bosses 13 upon the member5.

The flange 1d is provided with openings through which the standards 12project and a clamping means for holding member 5 against the valve ismounted upon the other upper ends. Such clamping means may be in theform of thumb-nuts 16 as shown in Fig. l and in such a case the upperends of the-standards 12 are screw-threaded. As shown 1n Fig. 2 cams 17may be employed in the place of the thumb-nuts .16, the said cams beingpivoted in bifurcations 1S formed in the upper endsof the said standards12.

The valve 7 is usually made in the-form of a flat plate of suitablemetal and may be Fig. 3 the opening may be partially or entirelyuncovered.

If preferred, the valve may be in the form of a flat plate 21 having ahandle 22, the

said plate being adapted to be thrust endwise between members '6 and 5of the mechanism and to extend between the standards 12. As shown inFigs. 5 and 6 a somewhat different type of clamping-means may be used ifdesired, within the scope of the invention. Thus as shown in said Fig. 5a loose ring 23 may be mounted upon the flange of the upper member 6 andbe formed with one or more inclined portions 24 adapted to act as camsand engage the under sides of heads 25 formed upon upright bolts 26.These upright bolts take the place of standards 12 shown in Fig- 1 andthe cam ring is provided with an operating handle 27 by which it may becontrolled for forcing the cam portions 2a beneath the heads 25. The

cam portions are also preferably provided with stops 28 for limiting themovements of the ring.

. In operation the lower member or cap ring 5 is put in position upon astand-pipe 9 and When it is not wished to take water therefrom the valveis closed and the clamping-means is set so as to force the upper member6 tightly against the valve. This will prevent any leakage of water fromthe stand pipe. .lVhen it is desired to take water from the stand-pipeand direct it to various points over the ground or in a field, an elbowas 29 of suitable size is put in positionin the opening of the uppermember 6.

Said elbow may rest upon a flange 30 as shown in Fig. 2 formed upon theinner sur- 7 face of said member 6 or the elbow may be provided withprojections as 31 which engage the upper edge of said member 6 as shownin Fig. 5, for preventing the elbow from resting upon the valve. Thesurface piping is connected with the elbow and extended in any desireddirection. -The valve is thenpulled outwardly from between the members 5and 6 and the water is permitted to flow into and through the elbow 29.The

weight of. the water in the elbow and adjacent piping is suflicient tohold the elbow in place and is usually sufficient to hold the member 6against themember 5 but if there is any leakage between the members, theclamping-means may be adjusted to force the members tightly together.hen ample water has been secured from said standpipe, the valve isforced between the memthen moved .to anotherfstand-pipe.

facilitating such movement and the water is thus out ofl". The elbow andpipe may be clamping-means may be always so adjusted as to preventleakage at the valve.

The 7 It will be understood that the cap ring or lower member of themechanism may be adapted to any kind of piping or stand- .pipe withoutdeparting from the spirit of the invention, and that the device may be iused with metallic or tile piping as well as cement concrete pipes. It,will also be evident that various kinds of clamping-means and valveslides 'may be used within the spirit of the invention. i

What is claimed is: 7 V l. A valve connection mechanism comprising apipe cap device, having separable cut off slide receiving membersandadapted to receive auxiliary piping and a cut oil slide adapted to forcethe said membersapart and enter between them to close the pipe outlet,

whether the auxiliary piping is engagii-ig the said connection mechanismor not.

2. A pipe end controlling device having a member fastened to the pipeand a cooperating member removably, held with respectthereto, guidemeans projecting from one member thereof and engaging and holding theother member and a valve plate adapted to force: the members apart andenter between them for controlling the outlet of the pipe.

3. A pipe connection valve mechanism comprising a pipe ring fixed to asupply pipe, an auxiliary pipe holding ring resting thereon and adaptedto hold an auxiliary pipe with respect to the supply pipe and a cut-offslide adapted to bear the and an auxiliary pipe therein, for slidingbetween the pipe rings to close the pipe outlet. i

, 4. A pipegconnection valve mechanism l-lilo comprising a memberadapted to be secured to the outlet of a pipe, guides projecting fromsaid member, an auxiliary pipe holding member loosely engaging saidguides, a.

weight of the auxiliary pipe holding ring let of the pipe and a valveslide pivotally engaging one of the exterior guiding studs and adaptedto be swung toa position between the members of the device forcontrolling the flow of materials through the piping held in theregister thereby.

6. A pipe connection valve mechanism comprising a member adapted to besecured to the outlet of a pipe, exterior guiding studs projectingtherefrom, an auxiliary pipe holding member having apertures engagingsaid studs, the said members having engaging valve seat edges, a valveslide adapted to be introduced between'said edges for controlling thepassage of materials through the piping and means engaging the ends ofsaid studs for clamping the said members upon said valve slide.

In testimony whereof, I have hereunto set my hand, in presence of twoWitnesses.
